Low cost actuators are simpler to apply
Low cost actuators provide a simple and low cost electrical alternative to fluid power actuators, and to electric drive systems employing ball screw or gear reducer mechanisms.
The Exlar Tritex Series of actuators from Inmoco provide a simple and low cost electrical alternative to fluid power actuators, and to electric drive systems employing ball screw or gear reducer mechanisms They combine a brushless servomotor, servo amplifier and position controller in a single industrial grade enclosure

INMOCO adds more industrial automation controllers
INMOCO has added seven new servo and stepper models to its popular MultiPro family of industrial automation controllers from Control Technology Corporation (CTC).
Brushless digital servos have SERCOS connectivity
Already 40% smaller than equivalent brushless digital servo drives, the Pacific Scientific all-digital PC800 range from Inmoco now offers more functionality, with SERCOS connectivity.
This integration overcomes the cost and complexity of a systems engineering approach, as all elements for producing linear motion have been properly matched and designed into the actuator and tested for their efficiency, said Inmoco.
Tritex actuators can be used for moving and/or positioning mechanical devices in a large variety of industrial or military grade applications.
They eliminate the requirement for pneumatic and hydraulic cylinders, the latter with its expensive support equipment and maintenance requirements.

Roller screws improve linear actuator performance
The new Exlar SR Series of linear actuators from INMOCO integrate patented roller screw technology with an integral brushless servo motor to provide high performance in motion control applications.
Instead, Tritex offer a cleaner more integrated unit that is easier to install and use, and provides improved positional performance and reduced cycle times.
The Tritex Series of electric actuators eliminates both the external servo amplifier and the expensive and failure prone cables associated with a typical servo system.
In addition, ball screw mechanisms, and separately mounted gear reducers are also ousted, because rotary to linear converters or mechanical reducers are designed into Tritex.
As a result, the time spent on component selection, design and installation is saved, and the panel space for a separately mounted amplifier - and its complex wiring - is not required.
Neither is trouble-shooting and debugging of components such as gear reducers, couplings and rotary-to-linear converter mechanisms.
Tritex linear actuators employ Exlar's patented, inverted roller screw mechanism for converting the rotational motion generated within the Tritex actuator.
This mechanism has a lead accuracy of 25 micron/300mm for high precision operation and can also be supplied with zero backlash.
The large contact area of the roller screw - the result of using rollers rather than balls - allows high force characteristics while guaranteeing long life - 15 times the life of comparably sized ball screws is common - even in the most demanding repetitive applications.
In addition, the planetary design of the roller screw allows it to be accelerated and rotated faster (up to 5000 rev/min) than comparably sized ball screws.
The Tritex Series actuators operate in one of five different motion producing modes, satisfying a wide range of applications in industrial automation, medical equipment, fastening and joining, blow moulding, injection moulding, testing, food processing, and more.
The modes include the following.
* Move To A Position (Or Switch).
* Move To A Preset Force Or Torque.
* Position Proportional To An Analogue Signal.
* Velocity Proportional to An Analogue Signal.
* Force/Torque Proportional to Analogue Signal.
Tritex non-volatile memory stores all programmed functions for a particular motion application, product configurations and motion parameters .
An RS/485 series interface allows control, programming and monitoring of all aspects of the actuator as it operates.
The Tritex actuators are available in stroke lengths from 75mm to 455mm, providing max continuous thrust capacities up to 5560N.
They are rated for operation at 24V and 48V DC; are available with many different types of mountings and offer IP54 levels of ingress protection. Request a free brochure from Inmoco ...
